Swift Code Not Saving image to core data

I want my swift code to save a image to core data right now that is not working but there are not runtime errors. Core Data Entity is named Info attribute is imp.

class DataBaseHelper {
    static let shareInstance = DataBaseHelper()
    let context = (UIApplication.shared.delegate as! AppDelegate).persistentContainer.viewContext
    func saveImage(data: Data) {
        let imageInstance = Info(context: context)
        imageInstance.img = data
        do {
            try context.save()
            print("Image is saved")
        } catch {
    func fetchImage() -> [Info] {
        var fetchingImage = [Info]()
        let fetchRequest = NSFetchRequest<NSFetchRequestResult>(entityName: "Info")
        do {
            fetchingImage = try context.fetch(fetchRequest) as! [Info]
        } catch {
            print("Error while fetching the image")
        return fetchingImage

Other class

    override func viewDidLoad() {
        let gwen = UIImage(named: "f.jpeg")
        if let imageData = gwen.self?.pngData() {
            DataBaseHelper.shareInstance.saveImage(data: imageData)

        let arr = DataBaseHelper.shareInstance.fetchImage()

        print("test number : ",arr)
